Brad Pitt may star, but it’s Austrian-born Christoph Waltz who steals the show in Quentin Tarantino‘s “Inglourious Basterds” (Lou Lumenick‘s review). The Viennese TV star, up to now unknown in the US, took the best actor prize at Cannes and should expect an Oscar nomination for his performance as a murderous but charming Nazi. At the Standard Grill party after the Cinema Society screening the other night, Waltz basked in adulation from luminaries John Stamos, Gina Gershon, Terrence Howard, Jennifer Esposito, Matthew Settle and his wife, Naama Nativ (who showed pic tures of their beautiful baby daughter, Aven), and Jonny Lee Miller, who starts Broadway previews next month with Sienna Miller (no relation) in “After Miss Julie.”
